GLENN F. COCH, OF ROCHESTER, NEW YORK, AlmlGNlJlt Il tl THE iitYMINGTN COM IPANY, F IQFEVV YlllittAv N, Y., A. CORPGRATIGN OF MARYLANDL ARTICULATED triplica-tion filed .lanuary The invention relates to journal bonus and has particular reference to stop means for taking; up any end thrust oit the journal and preventing distortion of the box as the result ot longitudinal movement of the journal with respect therto.

lt is well known that truck side trames move out et alinenient both horizontally and vertically when rounding curves, passing Crossovers, etc., under ordinary service conditions. rthis movement ot the sfide trames causes the journals to move longitudinally and to tilt vertically as well as laterally with respect to the journal boxes. lhe 2@general arrangement ot the journal, bearing` brass and wedge block in the journal bon such that endwise movement oli the journal toward the open end oit the bon brings an excessive strain upon the retaining lug,` on the bei; top or root, so that breakage elften results. lt is with these tacts in view that lh( ve designed the present invention which conten'iplates the provision ot a stop carried by the opposite sides et the bon and so positioned as to be normally out ot engagement with the journal but adapted to he engi; ged thereby ior taking up the end thrust and transmittingi` the strain to the sides oli the box instead ol' to the stop lug on the top or root.

Another object of the invention is to provide a journal stop embodying a thrust receivingstructure located in position to be engagged by the end ot the journal in the event ot longitudinal movement thereof; this structure including elements having a gimbal joint or connect-ion whereby the thrust receiving elenient may accommodate itsel't to the and ot the journal and bear flatly thereajniinst regardless oit whether the ournal be tilted laterally or vertically with respect to the box.

A further object of the invention is Vto provide ajournal stop torinedlol or embodying detachably connected sections held .normally in assembled relation by a supporting element reinovablyinounted within the journal bei;` the entire device constituting` an assembly and being' insertible in place and removable as such7 the parts being incapable ot separation while in mounted and operative position Still another object of the invention the provision oli a stop device ot this character which may be removed or replaced through the open end et the boxiwithout interference with any et the parts thereof.

Another object of the invention. is to pro- JGURNAL STOP.

Q1, 1925. Serial No. 3,868.

vide an articulated journal stop in which the relatively movable parts are provided with cmnparatively large coacting bearing; suraces so that they are capable ol" withstanding' great pressure without danger ot' breakage, the parts being` so mounted as to provide tor universal movement et the stop tace within the necessary or desirable range.

The invention further contemplates the provision ot a device ol this character which involves :tow parts preferably termed as castings and which may consequently be produced at small expense.

To these and other ends the invention coinprises the various elements and combinations of elements to be hereinafter described and set liorth in the claims hereunto appended.

Throughout the specification and drawings like parts are designated by like reference characters.

Referring;` more particularly to the drawinszs, the letter l designates a portion olf a journal bon including1 a rool B from which depends a lug1 C whicln under ordinary circun'istances, is engaged by certain elements within the journal bei; and is subject to great strain in the event oit longitudinal outward movement et the ournal l). ln carryingl out the present invention I provide a stop device, indicated generally at l, which includes a plurality ol sections so mounted as to take up the thrust in the event ot lengthwise move ment of the journal and prevent strain being transmitted to the lug C with probable damage t the roof.

In the present instance the stop device 1 is shown as including a supporting element or pintle 2, the axis of which is preferably substantially horizontal, a rotatable member 3 mounted thereon, and a roc-hable thrust rcceiving member 4. While the specitic construction of these members or sections may be varied, I have found it convenient to construct or form the meml'ier as a casting of elongated form and of substantially cylindrical shape and provided with a bore 5 through which .passes the supporting element 2 which is preferably ofcylindrical pin-like formation. Intermediate its ends the member 8 is provided with an open portion for a purpose to be described, and the upper and lower edges of said member are preferably provided withst'itliening flanges or webs 7. The end portions 8 of the member 3 constitute bearings which engage upon the supporting Y element or pin 2 while the intermediate portion 1s cored out or otherwise formed to provide a chamber or space 9.

The member 4 as shown includes a relatively large Wear platevportion carrying a U-shaped attaching Aportion 11 which may be integralv therewith and which is received within the space or chamber 9 when the stop is assembled, this U-shaped portion 11 also accommodatingA or embracing .the supporting element or 'pin 2 which passes therethrough and which serves as the means for connecting the members 3 and 4. The plate portion 10 may be reinforced byv providing the same with a pair of outstanding flanges 12 braced by webs 13. The outer surfaces of these flanges 12 are preferably arcuate to Yprovide trunnion portions and conform to the curvature of the corresponding bearing surfaces 14 at the upper and lower edges of the member 3. lVithin the U-shaped attaching portion 11, the plate portion 10 may be provided'with a vertical ridge 15 which Will serve as a fulcrum engaging the pin 2 and upon which the plate portion 10 may rock so'as to be capable of lateral tilting. For this reasonit is intended that the U- shaped attachingiportion 11 tit loosely upon the pin 2 and that the inner surface of its bight portion be beveled olf outwardly, as shown at 16, so as not to interfere with the lateral tilting movement. During any such tilting the flanges 12 will bear against the concaved bearing surfaces 14 of the memberI 3. From the' foregoing description it will be seen Ythat vthe stop plate 'is so mounted as to have universal movement, said mounting vconstituting a gimbal'joint.

For connecting the stop assembly to and within the journalY box, aV convenient arrangement is to provide inwardly extending bosses 17 on the inner faces of the side walls of the box A, these bosses being formed with vertically extending slots 18 and lt) which extend clear to the top. The slots 1S) are. of greater width than the slots 18 so as to accoi'nn'iodate the ends of the supporting element or pin 2 which has its extremitiesI eut away at opposite sides or otherwise formed to deline narrow extensions 20 located within the slots 18. r1`he slots l) are. ot slightly greater width than the diameter olf the pin 2 while the slots 18 are of considerably larger size than the thickness of the extensions 20. At one edge of each slot 18 may be provided a slight overhang 21 which defines a constricted entrance 22 to the slot, however, of sutiicient width to permit ready passage of the extension 20. By this arrangement it will be noted that when the pin 2 is in place accidental vertical displacement thereof will be prevented owing to the fact that tendeiuzy to `iove upwardly will be checked by engagement of the extensions 2O with the overhanging shoulders or ledges 21 whilel at the same. time the assembly may he removed by pulling it bodily upwardly and moving it toward the journal so that the extensions 20 will elea r the shoulders or ledges 21.

It is unnecessary for the member l to have a wide degree of rotative movement and for this reason I have shown it as provided at its ends with extensions 23 which project somewhat into the slots 1S). However, the width of these extensions is less than the width of the slots so that the member 2l may rotate to a sufficient extentto permit the plate portion 10 of the member 4 to accommodate itself to the end of the journal in case the. latter moves into engagement therewith at' such a time that its aXis is not in horizontal position. The location of these extensions within the slots will, however, operate to prevent the members 3 and 4 from turning to such :in extent as to drop out of place. The lateral turning movement of the member 4 so that the plate portion NlO thereof may confrnin to the end of the journal in case the latter engages'thereagainst while its axis is tilted into a position other than its normal transverse position has been described.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed and easily installed or removed journal stop formed of articulated sections and one in which the wear and thrust receiving member may accommodate itself at all times to the position of the journal in case the latter engages thereagainst, the advantage being that a flat bearing surface will he presented for taking up the thrust and transmitting it to the sides of the box, consequently avoiding the bringing of any undue strain upon other and weaker portions of the structure. In case of breakage of any part or wearing ont of the journal engaging member it is evident lon IUS

llt)

that the entire assembly is easily capable of bodily removal and subsequent separation` so that a new part may be substituted and the assembly reinstalled, all oit which operations may be accomplished in a simple and expeditious manner and without disturbing the journal boK or its connections.

W'hile l have shown and described the preferred'cnilmdiment oli' my invention, it is to be understoml that l reserve the rio; l
